What is this, in plain English?

When you use an AI coding assistant on a real project, a few things tend to go wrong. It re-explores the whole codebase from scratch every time you ask it something, burning time before it's answered anything. It forgets what you talked about the moment you close the chat, so you end up re-explaining yourself constantly. It jumps straight into writing code without checking what you actually meant — "vibe coding." It installs things on your computer without asking. And it hands you a finished piece of code that it understands but you never really did, which is a problem, because you're the one who has to maintain it afterwards.

agent-memory-kit is a handful of files you copy into a code project that fixes all five of those, at once. Think of it like handing a brilliant but forgetful new hire a company handbook, a notebook, and a habit of checking in before they do anything risky — except the "new hire" is your AI assistant, and the notebook is a folder on your own machine, not a server anywhere. Nothing to install as a service, nothing to sign up for, no data leaving your computer.

Try it in your project — one command, nothing left installed afterwards:

uvx agent-memory-kit-cli init

Then uvx agent-memory-kit-cli doctor tells you whether it worked. More options in Quick start.

Measured, not asserted — every number here is reproducible with a command in this repo:

Who it's for

• Developers who use an AI coding assistant daily and are tired of re-explaining the same context every session — or a little worried they don't actually understand all the code that's shipped in their name.
• Employees at large or regulated companies who want to use an AI coding assistant productively but can't install arbitrary software, don't have admin rights on their work laptop, and don't want to wait on an IT ticket or a security exception just to get started. This kit is built specifically so you don't have to ask permission to try it — see Requirements and Enterprise readiness below.
• Engineering leads, IT, and security teams, especially at companies where employees can't freely install software, who want AI-assisted coding to be safe, auditable, and not require a procurement process of its own.
• Anyone asking "is it actually safe to let AI write code here" — this kit is built to answer that question honestly; see SECURITY.md for the full, plain-language case.

Requirements

Nothing else. No API key, no account, no subscription, no server to stand up, no admin/root access at any point.

What you get, one line each

If none of that sounds like your problem, the rest of this README goes deep on how it works. If it does, the Quick start below takes about a minute.

Enterprise readiness

This kit was designed around one constraint: a developer at a large or regulated company should be able to adopt it without asking anyone for permission. That shapes everything else about it.

• No admin rights, ever. Every install writes to your own user account or the project directory — nothing needs sudo, nothing needs a Windows admin prompt.
• No new vendor to onboard. There's no company behind this collecting your data, no SaaS product to run past procurement, no data-processing agreement to negotiate, no subscription to expense. It's files, on your machine, under the MIT license.
• No telemetry, ever. Nothing phones home. Nothing is uploaded. The only network calls this kit ever makes are an install command you explicitly approve, a connectivity check that fetches nothing, and one explicit org-policy sync command — see SECURITY.md for the exact list, per skill.
• An audit trail when you need one. Every tool install/uninstall is logged locally to an append-only ledger with a best-effort software bill of materials, exportable as a portable report for a compliance review.
• Central policy without central control of every keystroke. An IT or security team can drop a single read-only policy file that allowlists or denylists specific tools, or routes installs through an internal package mirror — and no individual project can override that policy.
• A one-sitting security review. SECURITY.md is short enough to read end to end in about ten minutes: exactly what's read, what's written, and what (if anything) ever leaves the machine.

A drop-in AGENTS.md contract, a local codebase index, and five focused companion skills — cross-session continuity, propose-only tool access, a PRD/TRD discipline in place of vibe coding, a closing recap so the developer understands what an agent just shipped under their name, and an MCP bridge for hosts that aren't Claude Code — for AI coding agents working in real repositories. Install the whole kit, or just the pieces you want.

No daemon. No binary. No dependencies beyond Python 3.8+ — including the test suite (tests/, stdlib unittest). codebase-memory makes no network calls, period. Every other skill documents its own, narrower trade-off: session-memory, dev-recap, and spec-first make no network calls at all; tool-provisioning makes none either, except the install command you explicitly approve (or a doctor reachability probe that fetches nothing, or the one explicit sync-org-registry command); mcp-bridge is a local stdio process this kit starts itself, not a hosted service — and it's opt-in, like the other three: the rest of the kit works exactly the same with or without it installed.

See Enterprise readiness above and SECURITY.md for the full threat model.

The problem

An agent dropped into an unfamiliar repository explores by grepping and reading files. On a large codebase that burns tens of thousands of tokens before it has answered anything, and it still hallucinates paths and symbols because nothing grounds it. Left unguided, it also skips straight to code without writing down what it's building or why, ships a diff the developer never really understood, and reaches for whatever library seems convenient without asking.

The approach

Index the repo once into a local knowledge graph. Render the graph into three tiers, from cheapest to most expensive:

Then give the agent a contract (AGENTS.md) that makes it climb that ladder from the top, cite path:line for every claim, and verify before declaring anything done.

Five focused skills sit on that foundation, each independently installable, composing into one lifecycle rather than five separate tools bolted together:

A sixth skill, mcp-bridge, isn't a lifecycle stage — it's an alternate front door onto codebase-memory and session-memory for MCP-capable hosts that aren't Claude Code (Cursor, Claude Desktop, ...). See its own section below.

Reference numbers from the test suite: 286k LOC indexed in 2.0s single-threaded, producing a 1,650-token map. Structural queries return in ~0.1s.

Proof

A reproducible token comparison against two real, public repositories — psf/requests and django/django — running the same four "getting oriented" questions with and without codebase-memory:

python3 benchmarks/token_comparison.py --repo /path/to/any/repo --spec benchmarks/specs/django.json

No LLM calls, nothing hidden — full methodology, the exact grep-and-read naive baseline it's measured against, honest limitations (the naive baseline is capped at 6 files read per question, which understates its true cost — these ratios are a floor, not a ceiling), and raw JSON output: benchmarks/README.md.

Cheap is the easy half. Is it correct?

Token cost is the comfortable number to publish. The harder one is whether the thing recalled is the thing you wanted — so that gets measured too, over a shipped dataset, with the failures printed:

python3 evals/recall_eval.py --scorer tfidf   # the old behaviour
python3 evals/recall_eval.py --scorer bm25    # the new one, same dataset

Per query it is 5 better, 15 unchanged, 0 worse. The gain is concentrated where the old tokenizer was structurally blind: it lowercased before splitting, so getUserById became one opaque term and "where do we look up a user by id" recalled nothing. On that bucket of queries, recall@3 went from 0.700 to 1.000.

Three queries still miss, under both methods, and the harness prints them every run. "What did we make faster recently" shares no vocabulary with the entry recording a p95 drop from 1.8s to 220ms — a human sees it instantly, lexical retrieval cannot, and no parameter tuning changes that. Fixing it properly needs embeddings, which would mean a model download and the end of the zero-dependency property this kit exists for. That trade is refused on purpose, and the table is how you hold us to saying so.

Methodology, the authoring-bias disclosure, and why these numbers are not comparable to LongMemEval or LOCOMO scores: evals/README.md.

Case study: the same project, built twice

The benchmark above measures reading an existing repo. This measures building one, session by session, real commits included — a small URL shortener service (routes, storage, rate limiting, validation, tests), built as two separate public repos from the same feature list:

• linkshrink-baseline — same tasks, no kit, no PRD/TRD trail, no local index.
• linkshrink-agent-memory-kit — this kit installed from commit one, AGENTS.md's spec-first workflow followed throughout.

Both repos' app/ directories are byte-for-byte identical — same code, same tests, same outcome. What differs is what it cost to get there, tracked honestly in each repo's own SESSION_LOG.md as the work happened, not reconstructed after the fact: ≈1,430 tokens kit-assisted versus ≈1,993 without it — 28% lower — spent re-establishing context across four sessions of real, incremental feature work. Not the "half" this kit's own benchmarks show on a larger codebase (see Proof, above) — a project this small has little map to save on — and both SESSION_LOG.md files say so plainly, with a per-repo, line-by-line accounting of why, and a side-by-side COMPARISON.md committed to both.

How it compares

There are excellent tools in this space, and some of them beat this kit at things it does not try to do. Every fact below comes from each project's own README (checked 2026-09-17).

Pick codebase-memory-mcp for the most accurate code graph, if you can run a downloaded binary. Pick Serena if you want your agent to navigate and edit with language-server precision. Pick Mem0 if you are building an application that needs user and conversation memory.

Pick agent-memory-kit if:

• you can't install binaries, services, or language servers — a locked-down work laptop, no admin rights, no exception process;
• you want your agent's behaviour disciplined — evidence for every claim, a spec before code, no installs without a yes, a recap you can understand — not only its retrieval;
• you want memory across sessions with no LLM call, no vector store, and no network.

They also compose: nothing stops you running codebase-memory-mcp for the graph and this kit for the contract, the memory, and the guardrails.

Quick start

One command, from inside your project. Nothing is cloned, nothing is piped into a shell, and nothing is left installed afterwards:

uvx agent-memory-kit-cli init

Prefer a command that stays on your PATH?

pipx install agent-memory-kit-cli      # or: pip install agent-memory-kit-cli
amk init                 # install the kit here and build the index
amk init --hooks --mcp   # also: cross-session recall in Claude Code, live tools for any MCP host

Straight from GitHub instead of PyPI, pinned to a release: uvx --from git+https://github.com/sheikharfaz/agent-memory-kit@v0.6.4 amk init.

init copies the kit into the current repo, gitignores the two private paths (.agent/memory/session/, .agent/work/), builds the index, and prints the exact next commands for however you installed it. Then check it (example output):

$ uvx agent-memory-kit-cli doctor
agent-memory-kit doctor  ·  /home/you/project

  PASS  python 3.12.4
  PASS  git                   found
  PASS  kit files             all 25 present
  PASS  index                 412 files, 3,180 symbols -- OK
  PASS  privacy               .agent/memory/session/ is gitignored
  PASS  claude code hooks     wired
  PASS  claude code contract  CLAUDE.md loads AGENTS.md
  PASS  mcp server            registered in .mcp.json
  PASS  kit version           matches amk 0.6.4

0 failure(s), 0 warning(s).

With a permanent install (pipx/pip) the command is amk. With uvx, nothing stays installed, so write uvx agent-memory-kit-cli wherever this table says amk.

The package has no runtime dependencies, and installing it from PyPI pulls nothing else. (Installing straight from git instead builds it locally, which fetches the hatchling build tool once.)

Mind the -cli. This kit is agent-memory-kit-cli on PyPI. A package called agent-memory-kit also exists there, but it is an unrelated project by another author — don't install it expecting this one.

No outbound GitHub or pip? Clone and copy

Everything amk init does is also a plain file copy you can run from a checkout — the same file list, with no package manager involved:

git clone https://github.com/sheikharfaz/agent-memory-kit.git
cd /path/to/your/project
python3 /path/to/agent-memory-kit/install.py . --wire-hooks --wire-mcp
python3 .agent/skills/codebase-memory/index.py build

install.sh (bash) and install.ps1 (PowerShell) do the same. On a Windows image whose execution policy is Restricted — common, and not something a non-admin can change — use install.py; it needs no script-execution policy.

Or copy by hand; the complete list is FILES at the top of install.py. The core is AGENTS.md, .agent/lib/, and .agent/skills/codebase-memory/; every other skill directory is optional. Then add to .gitignore:

.agent/work/
.agent/memory/session/   # session-memory's local log -- raw prompt text, keep it local
# .agent/memory/          <- uncomment too if each developer should build their own index

Query CLI

python .agent/skills/codebase-memory/query.py <verb> — read-only, local, ~0.1s.

All verbs accept --limit N, --json, and --root <dir>.

find is the one to reach for when you can describe what you want but not name it. Identifiers are split, so plain words reach camelCase symbols:

$ query.py find verify a users password        # django/django, 6,901 files
0.42  django/contrib/auth/hashers.py:39   function  verify_password
0.26  django/contrib/auth/hashers.py:251  function  verify

That took 0.5s, with no embedding model, no vector store, and no language server. It is lexical ranking, not semantics — a symbol sharing no words with your phrasing will not surface, and find says so rather than pretending otherwise.

drift compares the current build against a past one using .agent/memory/history/drift-log.jsonl — one compact, derived-stats-only entry appended on every build (files/symbols/LOC totals, LOC by language, LOC by module; never file bodies). Shows what grew, what shrank, and which modules moved the most since your last build (or --last N builds ago). A no-op rebuild never adds a duplicate entry.

session-memory — cross-session continuity

codebase-memory knows the code. session-memory knows the conversation — an append-only local log of prompts and turns, searched by lexical (BM25) similarity, so a session that starts after an earlier one ended can recall what that session established.

python .agent/skills/session-memory/memory.py recall "what we discussed about auth"
python .agent/skills/session-memory/memory.py recent

Wired into Claude Code's SessionStart / UserPromptSubmit / Stop hooks (bash install.sh . --wire-hooks, or by hand — see SETUP.md), it runs without being invoked: every prompt is recorded and matched against every earlier session's entries in this repo, with related hits injected as context automatically. This is the "sits between the calls" behaviour — the agent gets relevant history without you or it having to remember it exists.

It is lexical similarity, not a trained embedding model: a hit shares real vocabulary with your query, not necessarily a paraphrased concept. Recalled entries get a small, capped ranking boost the more often they prove relevant (weight, bumped on recall) — a frequency heuristic that nudges toward what keeps mattering, not reinforcement learning in the ML sense, and never enough to override actual topical similarity. Every write passes through a best-effort secret redaction pass first, entries are capped and auto-pruned, and AGENT_MEMORY_KIT_DISABLE_SESSION_MEMORY=1 is a one-variable org-wide kill switch if a compliance policy requires one.

When both skills are installed, session-memory also layers a small freshness cache on top of codebase-memory: it stamps the map's generation at the end of every session, and if the next session's map hasn't changed, it says so instead of staying silent — an optional skip, offered only when there's real evidence nothing moved, never a reason on its own to trust a stale map. AGENTS.md's "read the map every session" default is unaffected for anyone who ignores the note. Detail: .agent/skills/session-memory/SKILL.md.

tool-provisioning — propose-only tool access

Detects that a task needs a tool/library/MCP server, and — only after you approve it in chat — installs it, lets the agent use it, then uninstalls it again. Nothing is ever installed silently.

python .agent/skills/tool-provisioning/toolkit.py doctor            # read-only: what's reachable here?
python .agent/skills/tool-provisioning/toolkit.py search "read a pdf"
python .agent/skills/tool-provisioning/toolkit.py plan pdf-text     # prints commands, runs nothing
python .agent/skills/tool-provisioning/toolkit.py install pdf-text  # only after you say yes
python .agent/skills/tool-provisioning/toolkit.py uninstall pdf-text

Every install is logged to a local ledger, with a best-effort SBOM fragment (name/version/license via pip show); uninstall reads its recorded command back from that ledger and refuses to act on anything not listed there, so it can never remove a package that was already on your machine before the kit touched it. list-installed / sweep recover from a task that ended before cleanup ran; export-audit produces a portable report for a compliance review. The registry is a small curated JSON file you extend per-project without touching the shipped copy — and an org can layer a read-only policy file on top (allowlist/denylist specific tools, or redirect installs through an internal package mirror) that a project's own registry cannot override; sync-org-registry is the one explicit, developer-run command that pulls it from a URL. doctor is a read-only preflight — is PyPI/npm/your mirror actually reachable from here, what CLIs exist, what proxy env vars are set — so a developer on a locked-down network self-diagnoses in seconds instead of opening an IT ticket. Detail: .agent/skills/tool-provisioning/SKILL.md.

spec-first — PRD/TRD instead of vibe coding

The difference between a brilliant engineer using AI and someone vibe-coding with it isn't speed — it's that the brilliant one still writes down what they're building and why before they build it. AGENTS.md §5 defines the workflow this backs: a PRD before Research, and a TRD-quality Plan artifact.

PRD.md (what, why)  →  research.md (what exists)  →  TRD.md (how, why this way)  →  progress.md

PRD.md is skipped only for a genuinely trivial, already-unambiguous request — not just because the developer said "just implement it" for something that isn't actually unambiguous; surfacing that ambiguity is the point. TRD.md holds the design to a stricter bar than a bare implementation plan: real alternatives considered and why they were rejected (the actual tell of senior-engineer thinking), a testing strategy mapped to each PRD acceptance criterion, a rollback plan, and blast radius.

python .agent/skills/spec-first/spec_first.py scaffold auth-retry   # writes PRD.md + TRD.md templates
python .agent/skills/spec-first/spec_first.py check auth-retry      # unchecked criteria, unanswered questions, missing TRD sections
python .agent/skills/spec-first/spec_first.py list                  # what's in flight, which artifacts exist

The script only scaffolds structure and checks it's filled in — writing the actual requirements and design is real thinking, the same way research.md and progress.md always required real work, not a form. Detail: .agent/skills/spec-first/SKILL.md.

dev-recap — closing recap and optional quiz

The other skills make the agent faster, safer, and better-planned. This one exists because the developer didn't write the code an agent just shipped for them, and a fast, well-cited diff is not the same thing as an understood one — see the "AI ethics stance" in its SKILL.md for the reasoning.

At the Definition of Done for anything beyond a one-line fix, the agent: gives a plain-English, junior-dev-pitched recap with path:line citations; grounds it in this repo's own conventions (codebase-memory, if built, or direct inspection otherwise); runs a heuristic gap scan; genuinely offers — never forces — a quiz or walkthrough; and always closes with an explicit assumptions & diversions line, even when it's "none." On the very first session in a repo, it's also the "new-hire week one" entry point: ask once how familiar the developer already is with this project, record it locally, and calibrate recap depth accordingly (a recorded veteran skips the 101-level framing).

python .agent/skills/dev-recap/recap_log.py gaps                 # heuristic: missing tests, new TODOs, unindexed files
python .agent/skills/dev-recap/recap_log.py record-recap --task auth-retry --files a.py,b.py --summary "..."
python .agent/skills/dev-recap/recap_log.py record-quiz --topic auth-retry --result understood
python .agent/skills/dev-recap/recap_log.py due-for-review        # spaced-repetition-lite: what's worth revisiting
python .agent/skills/dev-recap/recap_log.py set-familiarity --level new|some|veteran

The quiz questions themselves are generated live by the agent from the actual diff, not by a script — recap_log.py only logs the outcome (locally) and ranks what's worth a follow-up check-in later. Quiz and familiarity data answer one question, for the developer alone: nothing here reports results to a manager, a dashboard, or CI — see the SKILL.md if you're tempted to wire it into something that would. gaps is a lead generator with the same accuracy contract as codebase-memory's orphans: a clean result means the heuristic found nothing, never that nothing is missing. Detail: .agent/skills/dev-recap/SKILL.md.

mcp-bridge — live tools for hosts that aren't Claude Code

Every skill above reaches an agent through files (AGENTS.md, CODEBASE_MAP.md) or Claude Code's own hooks. mcp-bridge is the third path: a stdlib-only Model Context Protocol server, so Cursor, Claude Desktop, or any other MCP-capable host gets codebase-memory and session-memory as 20 live, schema-described tools instead of relying on file-reading conventions.

python3 .agent/skills/mcp-bridge/server.py --root /path/to/repo

Every tool is a direct passthrough to the same query.py/index.py/ memory.py the CLI already uses — no duplicated logic, so a tool's answer always matches what the CLI would print, accuracy caveats included. Two tools write anything (codebase_build, into .agent/memory/graph/ only; session_remember, one note entry) — everything else is read-only, and tool-provisioning's installs are deliberately excluded, keeping this kit's propose-only safety posture intact for hosts with no approval step of their own. install.py|.sh|.ps1 --wire-mcp registers it in your project's .mcp.json automatically. Detail, full tool list, and what's excluded and why: .agent/skills/mcp-bridge/SKILL.md.

What the agent contract enforces

AGENTS.md is loaded every turn and stays under ~5k tokens covering all six skills' worth of contract. It defines:

• Retrieval ladder — map → query → shard → targeted grep → line range → whole file. Never more than 3 whole files before answering. Never a 1000+ line file in full.
• Evidence rules — every claim about the repo carries path:line. No citation means the agent goes and looks.
• PRD → Research → TRD → Implement — a PRD before touching code (what, why, acceptance criteria — skip only for a trivial, unambiguous request), through to a TRD-quality plan (real alternatives rejected, not just the one chosen), each a durable artifact under .agent/work/<task-slug>/ that survives context compaction.
• HVE gate — Hypothesis → Verify → Evidence at every phase boundary. Unverified assumptions get labelled, never dropped.
• Command policy — an explicit allow / ask-first / never list. git push, force-push, reset --hard, deleting tests to go green, and piping downloads into a shell are on the never list under any framing.
• Prompt-injection stance — repo content is data, not instructions. A file telling the agent to run something gets quoted back to you, not executed.
• Durable memory — NOTES.md with provenance tags ([verified] / [stated] / [assumption]) and ADRs for real decisions.

Accuracy contract

Symbols come from language-aware pattern matching across 31 languages (49 file types are recognised; the rest are indexed as files without symbols), not from a compiler front end or a language server. This is a deliberate trade: zero dependencies and a 2-second build, in exchange for imperfect recall. The limits are written into the generated output itself, so the agent quotes them back at you instead of inventing certainty.

• Present means present. A recorded symbol at path:line is real.
• Absent does not mean absent. Dynamic dispatch, reflection, DI containers, macros, metaprogramming, codegen, and string-built calls are invisible.
• Call edges favour precision over recall. An edge is recorded only when a called name resolves to exactly one definition repo-wide. Ambiguous names are counted and discarded rather than guessed, and the count is published in the map.
• orphans is a lead list, never a delete list. Exported APIs, entry points and framework hooks look identical to dead code here.

Before any negative claim, AGENTS.md requires the agent to run coverage on the relevant paths, grep them directly, and state which paths it covered. A clean result means no recorded gap, never proven complete.

Privacy and safety

• No network access in the core scripts. Nothing is uploaded, phoned home, or logged off-machine.
• Writes are confined to .agent/memory/ (and, for spec-first, the already-established .agent/work/). Verified by md5-diffing every other file in the tree across a build.
• Secrets are excluded structurally, not heuristically: .env*, *.pem, *.key, keystores, *.tfstate, kubeconfig*, and anything matching *secret* or *credential* are never opened.
• Only paths, symbol names, and one-line signatures are written — never file bodies. Extracted strings that look like credentials are dropped.
• Three ignore layers: a built-in deny-list (node_modules, dist, target, caches, binaries, lockfiles, minified and generated files) → your .gitignore via git ls-files → a .agentignore you control.

Large repositories

# structure only, no call edges — fastest
python .agent/skills/codebase-memory/index.py build --calls off

# one package of a monorepo, in depth
python .agent/skills/codebase-memory/index.py build --root packages/checkout

Call edges are disabled automatically above 25,000 parsed files. Builds are full rather than incremental — simpler, safer, and fast enough that incremental wouldn't earn its complexity. Output is sorted and deterministic, so committing .agent/memory/ gives your team a shared map with clean diffs.

Compatibility

AGENTS.md is read directly by Codex, Cursor, recent GitHub Copilot, and many other agent harnesses. Claude Code is the exception: it reads CLAUDE.md, not AGENTS.md. So amk init (and install.py --wire-hooks) adds an @AGENTS.md import line to your CLAUDE.md — creating it if needed, appending if you already have one — which is the pattern Claude Code's own docs recommend. amk doctor checks it. .github/copilot-instructions.md is a thin pointer at the same contract, so Copilot picks it up either way. You maintain one contract, not three.

session-memory's automatic behaviour (the hooks, and the familiarity nudge riding on SessionStart) is Claude-Code-specific — that harness is what defines SessionStart / UserPromptSubmit / Stop hooks. Its memory.py CLI, and tool-provisioning's, dev-recap's, and spec-first's equivalents, are plain Python and work anywhere; other harnesses just have to invoke them by hand or via their own hook/skill mechanism instead of getting it for free. dev-recap and spec-first in particular are just AGENTS.md §5/§15 plus a CLI each — no hooks needed at all, so both work in any harness that reads AGENTS.md.

Or skip the hand-invoking entirely: mcp-bridge puts codebase-memory and session-memory behind the standard MCP stdio transport, which Cursor, Claude Desktop, and most other modern harnesses speak natively. --wire-mcp at install time gets you the closest thing to Claude Code's own hooks — live, schema-described tools instead of a CLI you invoke by hand — on any of them.

If you already run RPI-style chat modes (research/plan/implement), they compose directly: AGENTS.md §5 defines a PRD step before Research and a TRD-quality bar on Plan, with the same artifact slots your chat modes already expect.

What this is not

codebase-memory is not a language server, not an AST-accurate call graph, not semantic search. If you want tree-sitter accuracy across 162 languages and a proper knowledge graph from a single native binary, use codebase-memory-mcp, which is where several ideas here came from — the tiered agent profiles, the coverage-vs- completeness distinction, and the layered ignore model. This kit is the zero-dependency, regex-based version of the same idea, for people who want readable Python source they can audit — about 5,000 lines, no binary — including its own optional MCP server (mcp-bridge), a stdlib stdio process this kit starts itself rather than a hosted one.

session-memory is not semantic search either — its BM25 recall matches shared vocabulary, not paraphrased meaning, and it is not reinforcement learning in the ML sense; evals/ measures exactly where that ceiling sits and publishes the queries it still fails. tool-provisioning is not a package manager or a sandbox — it never installs anything without an explicit yes from a human in the current chat, and it never uninstalls anything it didn't itself install. spec-first is not a stage-gate or a template-filling exercise — a two-line TRD for a two-line change is correct, not lazy, and the PRD/TRD content itself is real thinking a script can't do for you. dev-recap is not a gate, a scorecard, or proof of correctness — the quiz is a comprehension check, not a test suite, gaps is a heuristic lead, not a guarantee, and the familiarity profile is for the developer's own benefit only; nothing about any of it blocks a task or reports to anyone else. mcp-bridge adds no new capability or accuracy of its own — it is a transport, not an engine; every answer it returns still carries the exact same caveats as the CLI verb it calls.

Testing

python3 -m unittest discover -s tests -v

Stdlib unittest only — no pytest, no test dependencies to install, so the "zero dependencies" claim holds for development too. Covers every skill's engine at the unit level (tokenizing, redaction, ranking, org policy, ledger semantics, PRD/TRD parsing) plus subprocess-level smoke tests that run the actual installers, hooks, and MCP protocol handshake the way a real client would. CI also runs evals/ on every push and fails if retrieval quality regresses below the numbers published above — the README cannot quietly go stale. CI (.github/workflows/ci.yml) runs the same suite on Ubuntu/Windows/macOS across Python 3.8 and 3.12 on every push and PR.

For security/procurement reviewers

See SECURITY.md for the full threat model, data-flow table, and what's explicitly out of scope. Short version: no telemetry, no network calls except a command you approve, nothing written outside .agent/memory/ and .agent/work/, zero third-party dependencies.

Documentation

Contributing

The most useful contribution is a real retrieval miss — something session-memory or amk find should have surfaced and didn't. The eval dataset was written by the maintainers, which is its biggest weakness, and the Retrieval miss issue template collects exactly what evals/ needs. After that: symbol patterns for under-served languages, and tool-provisioning registry entries. The constraints every change has to respect, and a PR checklist, are in CONTRIBUTING.md.
