## Summary
Full CLI audit + documentation accuracy pass. All 5 commits on this
branch:
### CLI Hardening (4 commits)
- **Clean errors instead of tracebacks**: corrupt manifests, missing
Docker, malformed JSONL, bad `--profile`, invalid env-var values all now
raise `click.ClickException` with helpful messages
- **Range validation**: ~25 numeric flags across 10 files now use
`click.IntRange`/`FloatRange` — `--port 0`, `--hours -1`, `--limit 0`
etc. produce clean usage errors instead of silent wrong behavior
- **Flag combination warnings**: conflicting combos (`--no-rate-limit` +
`--rpm`, `--no-optimize` + `--target-ratio`, `--telemetry` +
`--no-telemetry`) emit yellow warnings on stderr
- **`memory --db-path` default fixed**: was resolving to
`headroom_memory.db` (wrong bare file); now uses project store
`./.headroom/memory.db` if present, else `~/.headroom/memory.db`
- **`memory list --search` + filters**: `--scope`/`--session`/`--since`
were silently ignored when `--search` was also set; now filters are
applied to search results
- **`learn --verbosity --apply` now works**: the output shaper is off by
default (`HEADROOM_OUTPUT_SHAPER`); `--apply` now hot-enables it via
`POST /admin/runtime-env` on a running proxy, or prints explicit `export
HEADROOM_OUTPUT_SHAPER=1` instructions when no proxy is running
- **`perf --hours` overflow**: `1e9` hours no longer raises
`OverflowError`; treated as "all data"
- **`evals memory --categories` invalid input**: `abc,1,2` now raises
`BadParameter` instead of a raw `ValueError` traceback
### Documentation (1 commit, 20 files)
Corrected factual errors found by 3 parallel audit agents across root
docs, wiki, and the published Fumadocs site:
**Critical (caused runtime errors or wrong behavior if followed):**
- `simulation.mdx`: `plan.transforms_applied` -> `plan.transforms`;
`plan.savings_percent` -> computed from available fields (both raised
`AttributeError`)
- `shared-context.mdx`: `import { SharedContext } from "headroom"` ->
`"headroom-ai"` (5x `ImportError`)
- `claude-code-azure-foundry.mdx`: `pip install headroom` -> `pip
install headroom-ai`
- `api-reference.mdx` + `configuration.mdx`: `from headroom import
GoogleProvider` -> `from headroom.providers import GoogleProvider`
- `ccr.mdx`: CCR TTL default 300s -> 1800s (30 min)
**Fabricated flags removed:**
- `wiki/proxy.md` + `wiki/cli.md`: `--no-intelligent-context`,
`--no-intelligent-scoring`, `--no-compress-first` (none exist); replaced
with real CCR flags
- `wiki/configuration.md`: `--no-ccr-responses`, `--no-ccr-expansion`
(none exist); replaced with real flags
- `wiki/troubleshooting.md`, `wiki/metrics.md`,
`docs/troubleshooting.mdx`: `headroom proxy --log-level debug` (flag
doesn't exist)
**Stale content corrected:**
- `llms.txt`: telemetry stated as enabled-by-default (it's opt-in); wrap
list had 5 tools (now 11)
- `README.md`: compatibility matrix added 5 missing `wrap` targets;
`unwrap`, `doctor`, `init`/`install`, savings-analytics now mentioned
- `SECURITY.md`: supported version table showed 0.2.x (current: 0.27.x)
- `wiki/learn.md`: 5 missing flags added; verbosity shaper-off behavior
documented
- `wiki/quickstart.md`: "Configuration Reference" linked to `api.md`
(wrong) -> `configuration.md`
- `CacheAlignerConfig.enabled` default corrected: `True` -> `False`
- `opencode.mdx`: `--port` default wrong ("random") -> 8787; `openai`
backend removed
- `CONTRIBUTING.md`: broken Markdown table cell fixed
- `docs/meta.json`: `claude-code-azure-foundry` added to nav (was
unreachable orphan page)
- `configuration.mdx`: SDK modes vs proxy `--mode` now clearly
distinguished
## Test plan
- [x] `python -m pytest tests/ -x -q` — 857 passed, 0 failures
- [x] 41-combination CLI smoke test (all flag combos across 8 commands)
— 0 tracebacks
- [x] `ruff check` on all modified Python files — clean
- [x] Docs changes are removals/corrections of fabricated or stale
content; no new claims introduced

# Contributing to Headroom
|
|
|
|
Thanks for contributing! Please skim this before opening a PR : the policies exist because we've been burned skipping them, not because we love paperwork.
|

By participating, you agree to our [Code of Conduct](CODE_OF_CONDUCT.md).

## Where does my contribution go?
|
|
|
|
| Type | What to do |
|
|
| --- | --- |
|
|
| 🐛 Bug or small fix | **Open a PR** (with repro + test) |
|
|
| ✨ New feature / architectural change | **Open an issue or ask in Discord first.** |
|
|
| 🧹 Refactor-only | **Don't.** Only if a maintainer asked, as part of a concrete fix. |
|
|
| 🧪 Test/CI-only PR chasing a known `main` failure | **Don't.** We're tracking it. |
|
|
| 📦 New dep or version bump | **PR with written justification.** |
|
|
| ❓ Question | Ask in **Discord `#help`** |
|
|
|
|
**Open PR cap: 10 per author.** Get existing ones merged before opening more.
|
|
|
|
## Guiding principles
|
|
|
|
- **Verification is the author's job, not the reviewer's.**
|
|
- **Supply chain is a real threat.** Dependency changes get human review, every time.
|
|
|
|
## Bug fixes
|
|
|
|
Every bug-fix PR must include:
|
|
|
|
1. **A reproduction** — minimal code, failing test, or steps.
|
|
2. **A test that fails before your fix and passes after** (unit, integration, or e2e).
|
|
|
|
If you genuinely can't write a test, say so explicitly and explain how you verified.
|
|
|
|
## "Real behavior proof" — required on every external PR
|
|
|
|
We can't merge what we can't verify. Include a **`Real behavior proof`** section in the PR body covering:
|
|
|
|
- **Setup you tested on** (OS, Python, config, provider/model)
|
|
- **Exact command or steps you ran after the patch**
|
|
- **After-fix evidence** + **observed result**
|
|
- **What you did *not* test**
|
|
|
|
✅ Counts: screenshots, recordings, terminal output, copied live output, linked artifacts, redacted runtime logs.
|
|
❌ Does **not** count alone: unit tests, mocks, snapshots, lint, typechecks, green CI. Have them too — but they prove the test passes, not that the feature works.
|
|
|
|
**PRs missing this may be autoclosed.**
|
|
|
|
## New features
|
|
|
|
Before writing code:
|
|
|
|
1. **Open a feature-request issue** (or raise in Discord).
|
|
2. **Get a 👍 from a core maintainer** before implementing.
|
|
3. **Include a short spec** covering:
|
|
- **API surface** (public functions, config, CLI flags)
|
|
- **Changes to existing behavior**
|
|
- **User stories** — Given / When / Then, golden path + one edge case
|
|
- **Failure modes**
|
|
- **Recovery / resilience**
|
|
- **Security considerations**
|
|
|
|
Short and concrete beats long.
|
|
|
|
## Dependencies & supply chain
|
|
|
|
A human maintainer reviews every dep change. PRs that add or bump a package must justify:
|
|
|
|
- **Why this package** (vs. doing it ourselves / using existing deps)
|
|
- **Who maintains it** (activity, release cadence, security history)
|
|
- **Install surface** (transitive deps, native code, install/runtime network)
|
|
- **Why this version** — permitted reasons: **bug fix**, **security patch**, **required new functionality**. Cosmetic bumps will be closed.
|
|
|
|
## PR workflow
|
|
|
|
1. Fork, branch from `main`.
|
|
2. Install **Node 18+** and run `uv sync --extra dev` then `make install-git-hooks` — installs repo pre-commit checks on every commit, commitlint on every commit message, and ci-precheck on every push.
|
|
3. One logical change per PR.
|
|
4. Add tests.
|
|
5. `uv run pytest` · `uv run ruff check .` · `uv run ruff format .`
|
|
6. Update `CHANGELOG.md` for user-facing changes.
|
|
7. Open the PR with a clear description + `Real behavior proof` + any spec/justification required, and keep the PR in draft until the `Review Readiness` boxes are complete.
|
|
|
|
**Title format** (conventional commits): `feat:`, `fix:`, `docs:`, `test:`, `refactor:`.
|
|
|
|
**Commit message format** is enforced locally by the repo's `commit-msg` hook and again in CI.
|
|
|
|
**Review:** CI green, one maintainer review, coverage held/improved.
|
|
|
|
## Development setup
|
|
|
|
```bash
|
|
git clone https://github.com/chopratejas/headroom.git
|
|
cd headroom
|
|
python -m venv .venv && source .venv/bin/activate
|
|
node --version # Node 18+ required for commitlint hooks
|
|
python -m pip install --upgrade pip
|
|
python -m pip install -e ".[dev,relevance,proxy]"
|
|
python -m pytest
|
|
```
|
|
|
|
Headroom uses a `pyproject.toml`/`maturin` build backend. Older `pip`
|
|
versions may fail editable installs by looking for `setup.py`; upgrade `pip`
|
|
first or use `uv sync --extra dev`.
|
|
|
|
### Dev Containers
|
|
|
|
Two configs ship for VS Code / Codespaces:
|
|
|
|
- **`.devcontainer/devcontainer.json`** — Python 3.12, `uv`, Node.js, `gh`.
|
|
- **`.devcontainer/memory-stack/devcontainer.json`** — adds Qdrant + Neo4j sidecars (use `qdrant:6333`, `neo4j://neo4j:7687`).
|
|
|
|
Inside, use: `uv run ruff check .`, `uv run pytest`, etc.
|
|
|
|
## Optional automated review
|
|
|
|
This repository includes `.github/copilot-instructions.md` so maintainers can opt into GitHub Copilot code review without adding workflow billing noise to every PR.
|
|
|
|
Enable or disable automatic Copilot review in **Settings → Rules → Rulesets → Automatically request Copilot code review**. Keep it off unless maintainers explicitly want the extra review traffic.
|
|
|
|
## Coding standards
|
|
|
|
- [Ruff](https://github.com/astral-sh/ruff) for lint + format, line length 100, PEP 8.
|
|
- Type hints on public functions; Google-style docstrings.
|
|
- Cover new behavior + edge cases; aim >80% coverage on new code.
|
|
- Python 3.10+. Optional features go behind extras.
|
|
|
|
## Architecture principles
|
|
|
|
**Safety first:** never drop user/assistant content, never break tool call/response pairing, malformed content passes through unchanged, prefer false negatives.
|
|
|
|
**Performance:** transforms <50ms at P99, lazy-load optional deps, profile before optimizing.
