Changelog

1.6.0

Changed — the eight slash commands migrated to the skills format

Each commands/<name>.md now has a skills/<name>/SKILL.md twin with the same invocation name and a byte-identical body — confirmed against the current docs that a same-name skill takes precedence over the legacy command, so both formats coexist safely in this release (deleting commands/ is the 2.0 packaging break). Done for the features, not the deprecation notice:

• allowed-tools per skill — the resolved python3/python/py -3 script invocations (plus the CoWork ls /sessions/* fallback probe) are pre-authorized, so /echo-load, /echo-health, /echo-recall etc. stop prompting.
• disable-model-invocation: true on the write-heavy entry points (/echo-sweep, /echo-triage) — only the operator triggers them; the read-side skills stay model-invocable.
• argument-hint / $ARGUMENTS carry over unchanged (same semantics in SKILL.md bodies).
• The $ECHO path-resolution block stays per-skill: the skills format has no cross-skill snippet sharing (each skill directory is self-contained per the official docs), and the block is already the 2-line minimum.

Fixed — lint blind spot: retired trees masked by the leaf-README route

vault_lint.py checked retired patterns only for paths matching no route, so the permissive leaf-readme route (^(.+/)?README\.md$) absolved any seed README inside a retired tree — archive/ and _agent/outputs/ survived the 1.5.0 live cleanup unflagged. Retired patterns are now checked first: a path in a retired tree flags retired-path regardless of what else matches. New end-to-end test seeds archive/notes/README.md and asserts the flag (fails against the pre-fix linter, passes now).

Added — plugin.json completeness

homepage + repository → https://git.alwisp.com/jason/echo; manifest → 1.6.0.

1.5.1

Fixed — duplicate gate over-firing on vault-common tokens and cross-kind names

Live 1.5.0 use surfaced a false positive: creating the decision "echo-memory 1.5.0 improvement set" was blocked by the archived project echo-v-05 (score 1.0), because score = overlap / min(|tokens|) lets any entity whose single distinctive token appears in the new title score 1.0 — and "echo" appears across many entities in an echo-centric vault.

New echo_index.gate_candidates() (backed by token_df()) applies two precision rules before blocking; capture gates through it. fuzzy_candidates() — the advisory warning list — is unchanged:

• Same-kind only. A cross-kind name collision (a decision titled after its project, a meeting named for a company) is intentional naming, not a duplicate. Cross-kind lookalikes still warn, never block.
• No single-common-token blocks. A lone shared token gates only when it is unique to that entity (vault df == 1). Multi-token overlaps still gate even when the individual tokens are common.

Exit-76 / --merge-into / --force semantics unchanged. Tests: 3 new offline unit tests (gate_candidates), end-to-end gate cases restructured + 2 new (cross-kind no-gate, common-token no-gate); verified against the live vault (the original false positive now creates cleanly; a same-kind multi-token lookalike still gates).

1.5.0

Six improvements from the July 2026 review + the frontmatter-drift field report.

Fixed — capture-on-update kept only the first body line (silent data loss)

capture on an existing entity appended - <date>: <first line> and discarded the rest of the body. It now appends the whole body as a dated block — first line on the bullet, continuation lines indented under it. Idempotency (bullet-per-day) unchanged.

Added — frontmatter completeness (prevent → tool → detect → remediate)

A field audit found 18/71 entity notes missing status/tags; the drift was created at write time and invisible to the tooling. Four coordinated changes, driven by one data source (KIND_STATUS / KIND_REQUIRED_FM in echo_index.py):

• capture stamps a kind-appropriate default status (all kinds, not just projects) and seeds tags with the note's kind; new --tags a,b enriches it. Reflect/triage proposals accept a "tags" field.
• echo.py fm is now create-or-replace: on 400 invalid-target (missing key) it surgically inserts the one line into the frontmatter block and re-PUTs, verified — it previously failed on exactly the notes that needed repair.
• vault_lint.py gains a kind-scoped incomplete-frontmatter check (missing/empty status/tags on entity notes; block-style lists handled).
• sweep.py --apply backfills flagged notes (kind-default status + baseline tag).

Added — pre-write duplicate gate in capture

A strong fuzzy candidate (score ≥ 0.6, env ECHO_DUP_GATE) now stops capture before it creates a near-duplicate (exit 76 + candidate list) instead of warning after the file exists. --merge-into <slug> routes the capture as an update to the existing entity (mention learned as an alias); --force creates anyway. Weak resemblances still create + warn as before.

Changed — recall corpus + ranking (recall-index schema 2)

• The BM25 corpus now includes session logs and journal notes (down-weighted 0.5 / 0.4 so entity notes win ties) — past discussions are findable without having been promoted into an entity note. echo.py put keeps the index current for corpus paths.
• Ranking fuses BM25 with freshness (half-life decay on updated:, floored at 0.6, env ECHO_FRESH_HALF_LIFE) and status (active ×1.1, on-hold ×0.9, archived ×0.75) — a stale archived note no longer outranks the live one.
• Hits print updated:/status:; recall --json emits structured results.
• The recall index carries per-doc meta (schema 2); an old index is discarded and rebuilt automatically on the next recall/sweep.

Added — session hooks (self-firing load & reflect)

New hooks/hooks.json + two hook scripts. SessionStart runs echo.py load and injects the output as context (skips resume/compact; NOT-CONFIGURED degrades to an instruction, never an error). Stop nudges once per substantive session (≥5 user turns, env ECHO_REFLECT_MIN_TURNS) when nothing was reflected or session-logged — reflection itself still previews and asks before writing. Both use the 1.4.2 CoWork path fallback and always exit 0.

Added — one-tap inbox triage + --json on read verbs

New echo.py triage: --list --json parses the inbox into {line, date, text, age_days}; a proposals file (reflect schema + "line") is classified → previewed → applied via capture, with the inbox/processing-log/ audit line written per move (originals never deleted). /echo-triage rewritten around it. Also: --json for recall, link, and scope show (resolve/capture already had it).

Tests: +22 feature cases (mock end-to-end incl. hooks), patch-semantics updated for the new fm contract; all suites green. Docs: SKILL.md, README, command docs updated.

1.4.2

Fixed — CoWork sandbox plugin-path resolution

In a remote CoWork sandbox, ${CLAUDE_PLUGIN_ROOT} can resolve to a host path the sandbox can't reach (e.g. /var/folders/…), while the plugin is actually mounted under …/mnt/.remote-plugins/…. Every python3 "${CLAUDE_PLUGIN_ROOT}/…" invocation then failed until the agent manually located the real path. (Root cause is the harness env var, not the plugin — the scripts always used the variable correctly, never a hardcoded path — but the plugin now self-heals.)

• SKILL.md and all eight slash commands resolve the scripts path with a fallback: prefer ${CLAUDE_PLUGIN_ROOT}, else locate the copy under /sessions/*/mnt/.remote-plugins/*/skills/echo-memory/scripts/. Reused via $ECHO/$LINT/$SWEEP/$SDIR; on a normal host the primary path always wins, so behaviour is unchanged.
• echo-health / echo-sweep allowed-tools broadened to match the resolved (variable-dir) invocation and the ls/dirname resolver steps.

1.4.1

Fixed — baked credentials now win unconditionally

A per-user baked artifact could still be prompted for credentials on install. The baked DEFAULT_* tier was lowest priority, so a stale ECHO_* env var or a leftover/placeholder ~/.claude/echo-memory/config.json shadowed the baked key — even an unedited "<placeholder>" value won over it, flipping is_configured() to false and triggering the first-run "ask the operator" flow despite valid baked creds.

• echo_config.load() now treats a complete baked set (endpoint + key both present) as authoritative: it wins over env vars and the config file and cannot be shadowed. The generic (unbaked) plugin keeps its env → file → first-run flow.
• Added baked_complete(); source() reports baked-in (plugin) for that tier.

Security — untracked leaked baked artifacts

• Two labeled baked artifacts (echo-memory-1.4.0-jason.plugin, echo-memory-1.4.0-gretchen.plugin), each carrying a live vault bearer token, had been committed at the repo root. They are now git rm --cached-removed and .gitignore gains echo-memory-*-*.plugin so labeled builds can't be re-committed (the version-only pointer echo-memory.plugin and echo-memory-<ver>.plugin stay tracked). Tokens remain in prior history — rotate if the repo was ever shared.

1.4.0

Added — per-user baked-key builds (CoWork zero-touch)

The plugin is the only thing reliably mounted into a CoWork session (the sandbox's ~/.claude is synthetic, not your real one), so the config now can travel inside the artifact. echo_config gains a lowest-priority fallback tier — the DEFAULT_OWNER / DEFAULT_BASE / DEFAULT_KEY constants — empty in source, so the committed tree still ships zero credentials.

• build.py --bake-key --from <config.json> [--label <name>] substitutes a single user's owner/endpoint/key into those constants, producing a per-user artifact that needs no config file and no per-session paste. Values may also come from --owner/--endpoint/--key or ECHO_OWNER/ECHO_BASE/ECHO_KEY.
• Baked builds default to dist/ (gitignored) and never touch the shared echo-memory.plugin pointer.
• build.py --strip-key now force-blanks the same constants (guaranteed token-free).
• config show / doctor report [baked-in default] when a field resolves from the baked tier.

Changed — artifact hygiene

• .gitignore excludes dist/ and the filled-in echo-memory.config.json, where baked builds and the key file are meant to live. A baked artifact carries a vault key and must be delivered directly to that one user, never committed, pushed, or published. (Note: labeled baked artifacts built at the repo root were not yet guarded — see 1.4.1.)

Resolution order (unchanged for hosts)

env → $ECHO_CONFIG file → canonical ~/.claude/echo-memory/config.json → baked DEFAULT_*. On a normal desktop the empty defaults mean behaviour is identical to 1.3.x; the baked tier only matters in per-user artifacts.
